In contrast to the quantum world macroscopic considerations do not
allow for distinct coexisting path ways. A large number of effective
measurements [1]} must reduce ambiguities
to allow for a macroscopic description. In the two boundary description
these measurements must stored in the final boundary. This means that
the overlap
\(<\mathrm {inital}\,|\,\mathrm {final}>\sim 0.5^{\mathrm {decisions}}\)
